Applications
The SN74AHCT1G32DCKR is widely used in digital logic signal combining, bus arbitration, and enable/disable control circuits in portable electronics, industrial control systems, and communication equipment. Its single-gate architecture and tiny SOT23-5 footprint make it ideal for board-space-sensitive applications such as wearables, IoT modules, and battery-powered devices. It is also commonly employed in level-shifting and logic glue designs where a single OR function is needed without the overhead of a multi-gate package.

Frequently Asked Questions
What is the operating supply voltage range of the SN74AHCT1G32DCKR?
The SN74AHCT1G32DCKR operates over a supply voltage range of 2V to 5.5V, making it compatible with both 3.3V and 5V logic systems. The AHCT family accepts TTL-level inputs, so VIH is 2V and VIL is 0.8V at any supply voltage within this range.
What package does the SN74AHCT1G32DCKR come in and what are its dimensions?
It comes in a SOT23-5 (5-pin small-outline transistor) surface-mount package, also known by the JEDEC code R-PDSO-G5. This package measures approximately 2.9mm × 1.6mm with a pitch of 0.95mm, making it one of the smallest packages available for single-gate logic ICs.
What are common applications for the SN74AHCT1G32DCKR?
This single OR gate is commonly used in signal combining, enable logic, interrupt multiplexing, bus arbitration, and glue logic in digital circuits. Its compact SOT23-5 package makes it especially suitable for IoT devices, wearables, mobile electronics, and any application where board space is at a premium.
What are suitable pin-compatible or functional alternatives to the SN74AHCT1G32DCKR?
Functional alternatives include the 74LVC1G32 (lower voltage, 1.65V–5.5V), 74HC1G32 (CMOS inputs), and SN74AHC1G32 (standard AHC family). All are single 2-input OR gates available in SOT23-5. The AHCT variant is specifically chosen when TTL-compatible input thresholds are required alongside CMOS output drive strength.
